New York City is known as “The City That Never Sleeps”. While the excitement of the constant hustle & bustle may be a draw for some, it also can wear thin after a while. With over 8 million people in merely 302 square miles, there are bound to be some ruffled feathers. This projects seeks to understand noise complaints made to 311 from 2012 to 2018. We look for patterns based on time, attributes of populations within zip codes, and the effect of music venues on the complaints made in their local environments.

What are the Correlations between Noise Complaints and Demographics?

We created an overall correlation graph to understand the relationships between 311 noise complaints and selected demographic variables over time. The number of housing units and the total population immediately jump out as the most correlated, but interestingly so does the population under the age of 18.

Digging Deeper: How do the Correlations Vary by Zip Code?

We explored the most correlated variable by zip code to see if there were any neighborhood patterns. We also visualized the correlation between noise complaints and population under 18 at this level to discover geographic variation.

How do Noise Complaint Patterns Change Over Time?

We created a Heat Map to understand how noise complaints to 311 have evolved in NYC from 2012 to 2018, and to reveal any patterns that happen each year. The map displays that there has been a general increase in noise complaint calls to 311 over the 7 year period. Additionally, it looks like there are more noise complaint calls placed to 311 during the warmer months (approximately April to October), and that there are generally more calls placed on the weekends than during the week.

Digging Deeper: The Relationship Between Bachelor’s Degrees and Noise Complaints

There is a positive relationship between the number of people in a zip code with Bachelor’s Degrees (or higher) and the number of noise complaints in that zip code. There is a large concentration of zip codes with few Bachelors degrees and few noise complaints, and then as the number of Bachelor’s degrees in a zipcode increases, the minimum number of noise complaints increases as well. It’s interesting to note that the upper end of the noise complaint range seems to be concentrated towards the lower end and middle of the number of people with bachelor’s degrees range, not the upper end.

Digging Deeper: The Average Number of Noise Complaints Among the Richest and Poorest Zip Codes

There wasn’t as strong of a relationship between median income and noise complaints as there was between some of the other census variables and noise complaints, so we decided to look at the relationship more closely to learn about what was going on. We isolated the richest and poorest zip codes and compared the number of noise complaints per capita from each group over time.
There is a general increase in the number of complaints from both rich and poor zip codes over time, which was consistent with other analyses. At first, the richest and poorest zip codes had similar noise complaints per capita. Then, from 2013 to 2016, the richest neighborhoods had more noise complaints per capita than the poorest neighborhoods. However, something changed in 2017 and 2018, causing the poorest zip codes to have more noise complaints than the richest zip codes. More research is needed to discover the cause of this change and if it will stay the same in future years.

The Plot Thickens: Investigating The Relationship Between Kids and Noise Complaints

As highlighted in the correlation graph and map, on first inspection there was a positive correlation between the number of people under age 18 and the number of noise complaints in a given zip code each year. However, it looked as though the opposite became true once you started controlling for population within the variables. When we examined the relationship between the percent of the population under age 18 and the number of noise complaints per capita, we found that increasing the percent of kids in a zip code correlates with a decrease in the number of noise complaints per capita.

Do music and nightlife venues affect 311 noise complaints?

Another factor contributing to New York City’s reputation is the nightlife, of which live music is a contributor. Perhaps music and nightlife will be reflected in 311 complaints.

The choropleth map displays the number of music venues in each ZCTA. (The music venue data obtained from Ticketmaster’s Discovery API.) It is pretty clear that the ZCTAs with the highest concentration of venues are in Manhattan, from Midtown and south, and in ZCTAs in Brooklyn and Queens along the East River. Over 50% of the ZCTAs do not have a venue at all. The map makes it clear that venues are lacking in eastern Queens and the Bronx, southern Brooklyn and Staten Island. This is not too surprising as these areas tend to be residential or industrial.

The red dots cover areas that are approximately 1000 foot in radius from five established music venues in New York City. These venues are Madison Square Garden, the Apollo Theater, Terminal 5, the Bowery Ballroom, and the Kings Theatre. Clicking the red dots provide summary information about the venue, including capacity and number of 311 noise complaints within 1000 feet of the venue between 2012 and 2018.

Conclusions

This project sought to highlight the patterns in 311 noise complaint data in New York City. We explored the connections between music venue locations, population attributes, time, and noise complaints. Recommendations for further research include understanding more about cause and effect: Are certain people more likely to make noise complaints than others? Or are there certain people, locations, and behaviors that are more likely to cause complaints than others? Do the attributes of a certain zip code attract people who are more or less likely to make noise complaints? Or do they adjust their behavior to the pre-established norms of a neighborhood? Have people become more familiar with 311 over time, and thus become more likely to call in complaints? Or have the noise levels in NYC truly increased over time?
